(0,8),(1,6),(2,4),(3,2),(4,0).......
take any two points and find a equation of straight line given 2 points

(0,8),(1,6)

Solved by pluggable solver: FIND EQUATION of straight line given 2 points

hahaWe are trying to find equation of form y=ax+b, where a is slope, and b is intercept, which passes through points (x1, y1) = (0, 8) and (x2, y2) = (1, 6).
Slope a is .
Intercept is found from equation , or . From that,
intercept b is , or .

y=(-2)x + (8)

Your graph:

a equation is:

check for other two points

(3,2),(4,0)
